Specifically, the adjusting handle 125 is connected to the handle rotating shaft 121, when the adjusting handle 125 is rotated, the handle rotating shaft 121 rotates along with the adjusting handle, the scale 126 has a plus region and a minus region, when the adjusting handle 125 is in the plus region, the air inducing hole 128 below the adjusting handle 125 cannot be opened, only the gap between the seed picking knife and the seed suction hole 31 is adjusted, and the smaller the number is, the smaller the gap is. When the adjusting handle 125 is in the negative sign area, the air inducing hole 128 (the dotted line indicates the position) below the adjusting handle 125 is gradually opened, the larger the number is, the larger the opening of the air inducing hole 128 is, and meanwhile, the gap between the seed picking knife and the seed suction hole 31 is also smaller, so that the seeding requirements of seeds with different diameters can be met, and the redundant seeds can be blown off by air introduced through the air inducing hole 128.
The wave teeth 43 are used for supporting the seeds in the seed suction hole 31, and because the seeds adsorbed in the seed suction hole 31 are scraped strongly by other seeds in the seed storage chamber 52 when the seed suction hole 30 rotates, the wave teeth 43 support the seeds adsorbed in the seed suction hole 31. In this embodiment, the top of the outer anchor ring of wave tooth 43 avoids puncturing other seeds for circular-arc, in addition, wave tooth 43 top is to the direction of rotation skew, in this embodiment, inhales the clockwise rotation of kind of a dish, and wave tooth 43 top is to the clockwise deflection for the bearing capacity of the cell body arc of formation between two adjacent wave teeth 43 to the seed is better.
As shown in FIG. 5, the opening of the air guide ring 21 on the friction-reducing sealing disk 20 is 120-150 degrees, and the air guide ring 21 is connected with the negative pressure pipe 11, so that the negative pressure pipe 11 always provides negative pressure for the cavity of the air guide ring 21. After the seed suction hole 31 of the corresponding seed suction disc 30 rotates to the position corresponding to the air guide ring 21, the negative pressure provided by the air guide ring 21 in the seed suction hole 31 attracts the seeds in the seed storage chamber 52, so the seeds are attracted to the seed suction hole 31 and rotate along with the seed suction disc 30, and after the seed suction disc 30 rotates to the position where the seed suction hole 31 is separated from the air guide ring 21, the negative pressure in the seed suction hole 31 disappears, and the seeds fall off from the seed suction disc 30. In addition, since the seed suction disc 30 is in a rotating form, the seed suction disc 30 has the centrifugal force generated during the rotation process and the gravity of the seeds, so that the seeds can be separated from the seed suction disc 30.
As shown in fig. 6 and 7, a seed guide block 22 is provided at the end of the seed discharging position on the air guide ring 21, and the seed guide block 22 is used for guiding seeds. Specifically, if the seeds are completely developed and the particle size of the seeds is small, the seeds can pass through the seed suction holes 31 and enter the air guide ring 21, the seeds can freely fall to the seed guide building blocks 22, and the seeds are guided by the seed guide building blocks 22 and discharged out of the high-speed hole type combined air suction seeding unit. In addition, because the seed guiding building block 22 is triangular, when the seed sucking hole 31 passes through the position of the seed guiding building block 22, because the part of the seed sucking hole 31 is shielded by the seed guiding building block 22, in the rotating process, the area of the seed guiding building block 22 shielding the seed sucking hole 31 is gradually reduced, therefore, when the seed sucking hole 31 enters the corresponding area of the air guiding ring 21 from the outside of the air guiding ring 21, the seed sucking hole 31 can be seen as being gradually opened, the attraction to the seeds is gradually increased, and the seeds are prevented from being damaged due to sudden change of the seeds under pressure.

The adjusting plate 551 is used for adjusting the size of the seed filling opening, and the seed filling opening is large for seeds with large diameter, so that the seeds can enter the seed storage chamber 52 favorably, otherwise, the seed filling surface is too low, and the seed filling is not favorable; for small-diameter seeds, the seed filling port is closed, so that the seed filling surface is not too high, and the seeds are not difficult to separate from the population. During adjustment, the second waist-shaped hole 552 rotates around the hinge above, and the size of the seed filling opening can be adjusted.
The inboard bottom of casing 50 is equipped with picks subassembly 56, should pick kind subassembly 56 including picking kind of sword, first dead axle and first torsion spring, it is rectangular shape to pick kind of sword, the first end of picking kind of sword articulates at casing 50 inboardly through first dead axle, first torsion spring suit is on first dead axle, and the first end of first torsion spring is connected on picking kind of sword, the second end butt of first torsion spring is on casing 50, the second end setting of picking kind sword is in the corresponding seed suction hole 31 department of seed suction disc 30 lateral surface, this seed picking sword is used for rejecting and remains in the inboard seed of seed suction hole 31.
The seed picking knife is arranged at the position where the seeds fall from the seed suction disc 30, namely after the seeds are normally discharged through the seed discharging port, the seed suction hole 31 further rotates and moves to the seed picking surface of the seed picking knife, the seed picking surface of the seed picking knife is attached to the outer side plane of the seed suction hole 31 of the seed suction disc 30, if a crushed seed is adsorbed on the seed suction hole 31, the crushed seed can be inlaid on the seed suction hole 31 during seed discharging and cannot fall off, the next seed suction hole 31 cannot suck the seed, and therefore the crushed seed can be cleaned by the seed picking knife without influencing the next seed suction. The first torsion spring is used for slowing down impact force generated in the seed picking process of the seed picking knife.
